Expert writing Tips
Best practice
When indicating a duration, use "for a longer time" or "since a longer time ago" instead of "since longer" to ensure grammatical correctness and clarity.
Common error
Avoid using "since" directly before adjectives indicating duration. "Since" typically introduces a specific point in time, not a length of time. Instead, use "for" to express duration: "for longer periods" is correct, while "since longer periods" is not.

Ludwig's WRAP-UP
While the phrase "since longer" appears relatively frequently across various sources, including scientific and news outlets, Ludwig AI analysis indicates that it is generally considered grammatically incorrect. The intended meaning is to express a duration of time, but "since" is typically used to denote a starting point, not a length of time. Therefore, it is recommended to use alternatives such as "for a longer time", "for an extended period", or "since a longer time ago" to ensure clarity and grammatical correctness. Ignoring this advice may lead to misinterpretations and a perception of lower writing quality.
